Popis: Prevalence of dementing illnesses is expected to grow due to aging of the population throughout the world. Vascular dementia and Alzheimer's disease share several risk factors and are nowadays considered two ends of a continuum rather than two distinct entities. Traditional cardiovascular risk markers such as diabetes, dyslipidemia, hypertension, metabolic syndrome and adiposity in mid-life are harbingers of cognitive decline, Alzheimer's disease and vascular dementia later in life. In aged populations, only diabetes has been more constantly associated with the development of cognitive dysfunction, while other risk markers have shown more mixed results. Normal aging, co-morbidities and other changes connected to cognitive decline make the interpretation of the risk markers in the elderly challenging and probably explain these contradictory findings. Control of cardiovascular risk factors has been linked to beneficial effects in terms of cognition in cross-sectional and prospective follow up studies, but the results of interventional trials have been disappointing. More research in this area is needed, specifically, placebo-controlled randomized trials in both mid-life and late-life with cognitive dysfunction as a primary endpoint.
